7001033: assert(gch->gc_cause() == GCCause::_scavenge_alot || !gch->incremental_collection_failed())
7002546: regression on SpecJbb2005 on 7b118 comparing to 7b117 on small heaps
Summary: Relaxed assertion checking related to incremental_collection_failed flag to allow for ExplicitGCInvokesConcurrent behaviour where we do not want a failing scavenge to bail to a stop-world collection. Parameterized incremental_collection_will_fail() so we can selectively use, or not use, as appropriate, the statistical prediction at specific use sites. This essentially reverts the scavenge bail-out logic to what it was prior to some recent changes that had inadvertently started using the statistical prediction which can be noisy in the presence of bursty loads. Added some associated verbose non-product debugging messages.

26 # The cscope.out file is made in the current directory and spans the entire | |
27 # source tree. | |
28 # | |
29 # Things to note: | |
30 # 1. We use relative names for cscope. | |
31 # 2. We *don't* remove the old cscope.out file, because cscope is smart | |
32 # enough to only build what has changed. It can be confused, however, | |
33 # if files are renamed or removed, so it may be necessary to manually | |
34 # remove cscope.out if a lot of reorganization has occurred. | |
